They are located in the lateral, third and fourth ventricles and their barrier function is attributed to the tight junctions between the epithelial cells, in addition to the metabolism and efflux that occurs within the tissue itself (Strazielle et al., 2004). However, the molecular composition of the intercellular junctional complexes and the transporters present at the BBB (Gazzin et al., 2008) differ from that on the blood–CSF barrier, which means that drug movement into the brain varies depending on its main route of entry. Consequently, although the CSF is an accessible body fluid that provides insight into the brain infection and drug penetration, it can also diverge in important ways from the brain itself. An understanding of anti-HIV drug movement across both the BBB and the blood–CSF barrier is therefore of special interest.","tracks":[{"project":"2_test","denotations":[{"id":"19176219-15381331-99578268","span":{"begin":413,"end":417},"obj":"15381331"},{"id":"19176219-15381331-99578268","span":{"begin":413,"end":417},"obj":"15381331"},{"id":"19176219-18680196-99578269","span":{"begin":553,"end":557},"obj":"18680196"},{"id":"19176219-18680196-99578269","span":{"begin":553,"end":557},"obj":"18680196"},{"id":"19176219-15381331-3576922","span":{"begin":413,"end":417},"obj":"15381331"},{"id":"19176219-15381331-3576922","span":{"begin":413,"end":417},"obj":"15381331"},{"id":"19176219-18680196-3576923","span":{"begin":553,"end":557},"obj":"18680196"},{"id":"19176219-18680196-3576923","span":{"begin":553,"end":557},"obj":"18680196"}],"attributes":[{"subj":"19176219-15381331-99578268","pred":"source","obj":"2_test"},{"subj":"19176219-15381331-99578268","pred":"source","obj":"2_test"},{"subj":"19176219-18680196-99578269","pred":"source","obj":"2_test"},{"subj":"19176219-18680196-99578269","pred":"source","obj":"2_test"},{"subj":"19176219-15381331-3576922","pred":"source","obj":"2_test"},{"subj":"19176219-15381331-3576922","pred":"source","obj":"2_test"},{"subj":"19176219-18680196-3576923","pred":"source","obj":"2_test"},{"subj":"19176219-18680196-3576923","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#93aeec","default":true}]}]}}
